TROLLEYrWIRE HANGER.

To all whom it may concern:

or other overhead structure, and it has for its object to provide a combination of devices which may be readily installed and free from liability to breakage or disarrangement, and also be particularly adapted to withstand the deteriorating efiects of moisture and other atmospheric conditions.

In the accompanying drawin Figure 1 is a vertical, sectional view of a trolleysupporting structure embodying my invention, and Fig. 2 is a plan view of the trolley car and a portion of the wire to which the ear is attached.

Referring to the structural details shown in the drawings, the trolley ear 1 is provided at its lower side with gripping members 9, that are bent around a trolley conductor 3 in the usual manner, and the upper end of the body member is provided with transverse slots 4- at opposite sides of the internal recess 5, the latter being screwthreaded to engage the screw-threaded lower end 6 of a stud 7, the upper portion of the stud being seated in an insulating body 8, and being provided at an intermediate point, just below the body 8, with a shoulder or flange 9. Seated against the shoulder or flangeQisaring 10 that is preferably formed of steel and has a tapering inner surface to engage a correspondingly tapered outer surface of the upper portion of the body member of the ear 1. The insulating body 8 is contained in, and supported by, a metal casing or frame 11 having laterally projecting arms 12 for attachment to a span wire or other overhead supporting means.

The recess 5 in the ear 1 is of such dimensions as to screw loosely upon the stud 6, so that, when it is screwed into place, the tapering inner surface of the ring 10 will force the sides surrounding the recess in Specification of Letters Patent.

wardly to firmly grip the stud and anchor the ear securely in position, this action being permitted by reason of the slots l. By reason of the fact that the tap hole in the ear is slightly larger than the stud and by reason of the slots in the ear, at least a half turn of the ear may be made after the ring 10 is forced against the shoulder 9 of the stud, this construction being such as to insure a proper relation of the parts and an extremely rigid connection, as well as'one which is protected from the weather.

I claim as my invention:

1. A trolley wire hanger comprising, a downwardly projecting stud having a screw threaded lower end and an intermediate vmediate shoulder, of a trolley ear having a transversely slotted body provided with an externally tapered upper end and a lower end adapted to grip a trolley conductor, a scren threaded recess to engage the screw threaded end of said stud, and a ring adapted to engage the stud shoulder and having a tapered inner surface to engage the tapered surface of theear.

3. The combination with a stud having a screw-threaded end and an intermediate shoulder, of a ring adapted to engage said shoulder and having a tapering inner face, and a trolley ear adapted to grip a trolley conductor having a transversely slotted body to be engaged by said ring'and provided with a screw threaded recess to engage the screw-threaded end of said stud.

4-. T he combination with a stud having a screw threaded end and an intermediate shoulder, of a ring adapted to engage said shoulder and having a tapering inner face, and a trolley car adapted to clamp a trolley conductor and having only its upper portion transversely slotted, said portion being adapted to be engaged by said ring and provided with aserew threaded recess to subscribed my name this 21st day of Nov.

loosely receive the screw threaded end of 1911. said stud, whereby relative movement of said ear and said stud is permitted after 5 engagement of said ring and said shoulder Witnesses:

is effected. JOHN S. DEAN, In testimony whereof I have hereunto B. B. HINES.
